universe (English)

Where does "universe" come from?

The English word 'universe' traces back through Middle English 'universe' and Old French 'univers'[1][2]. These forms derive from the Latin 'universum', meaning 'all things, as a whole, the universe'[1]. This Latin noun is the neuter form of 'universus', which means 'all together, whole, entire, collective, general' and literally translates to 'turned or combined into one'[1]. The Latin compound brings together 'uni-', a combining form of 'unus' meaning 'one', and 'versus', the past participle of 'vertō' meaning 'to turn'[1].
